- All incident cases of diabetes mellitus in the age group 15 to 34 years have been prospectively registered in Sweden since January 1983. To analyse the utilization of outpatient services 8 years after disease onset, we selected the cases registered in 1983 and two controls per case from the general population, matched by age, gender, and county of residence. In 1991, retrospective data about utilization patterns during a 3-month period were collected via a mailed questionnaire, returned by 317 (72%) patients with diabetes and 586 (68%) controls. Seventy-four percent of the cases and 19% of the controls reported at least one visit to a hospital outpatient clinic, including accident and emergency departments. The odds ratio for one visit was 14 (95% CI 9.6-20), for two visits 11 (95% CI 7.0-18), and for three or more visits 8.9 (95% CI 5.6-14). Even when specialized diabetes clinics were excluded from the analysis, the cases had higher odds for visits to internal medicine clinics, to ophthalmology clinics, and to gynaecology clinics, but not for visits to surgical clinics or to accident and emergency departments. Of non-hospital outpatient services, only visits to nurse practitioners were reported by a higher percentage of diabetic responders. Twenty-seven percent of patients with diabetes, as compared to 9% of the controls, had visited both hospital and non-hospital outpatient offices. Females were overrepresented among diabetic high-consumers. The results indicate that most young to middle-aged Swedish persons with diabetes are monitored at hospital outpatient offices, but considerable overlap exists between hospital and non-hospital outpatient services. Further research is needed into the determinants of utilization patterns in diabetes, such as gender.

- –To analyse the cause of death pattern in the cohorts of women included in the Swedish randomised mammography screening trials by comparing the groups of invited and control women both with each other and with the general population of Swedish women. Setting –Since 1977 four randomised trials of mammography screening have been performed in Sweden: Malmö, Kopparberg and ÖOstergötland (the two county trial), Stockholm, and Gothenburg. Design –Overview of four randomised mammography screening trials. Results –The total numbers of deaths in the invited and control groups respectively were 15 695 and 11 887 corresponding to a relative risk (RR) of 1.00. There were no significant differences between the invited and control groups for cause-specific mortality, except for breast cancer. When the total mortality in the invited and the control groups was compared with that for Swedish women in general the standardised mortality ratio was close to 100. Conclusions –The cause of death pattern in the invited group was, except for breast cancer, very similar to that in the control group, showing that the groups were comparable. Similarly, the total mortality including breast cancer mortality in the control group was almost identical to that in Swedish women in general. The same was true, with the exception of breast cancer, for the invited group. These observations confirm that the trial cohorts are representative of Swedish women and indicate that the quantitative results from these trials may safely be generalised to the Swedish population.
